“…4 Similar results were reported by Gunther at al 5,6 and Murphy at al 7 Palmaz at al reported that the patency rate for the Palmaz stent at 8.7 months was 92%, and others have made a similar observation. [8][9][10][11][12] In the present study, the initial procedural success and patency rates (95% and 97%, respectively) are comparable with previous reports [4][5][6][7][8][9][10][11][12] and are considered equal to, or even superior to, the results obtained with the Wallstent or Palmaz stents.…”

“…Vorwerk et al reported a 4-year patency rate of 78% and 82% for the primary and secondary stenting procedures, respectively, in 100 patients (13, 28). Cikrit and colleagues reported a 5-year patency rate of 63% in 38 limbs that were treated by Palmaz stent placement, whereas Palmaz et al initially reported a 92% patency rate at 9 months (29). Primary 4-year patency rates as high as 86% have been recently reported (7, 30).…”

Stent Placement for Chronic Iliac Arterial Occlusive Disease: the Results of 10 Years Experience in a Single Institution

ObjectiveWe wanted to retrospectively evaluate the long-term therapeutic results of iliac arterial stent placement that was done in a single institution for 10 years.Materials and MethodsFrom May 1994 to April 2004, 206 patients who underwent iliac arterial stent placement (mean age; 64±8.8) were followed up for evaluating the long term stent patency. Combined or subsequent bypass surgery was performed in 72 patients. The follow up period ranged from one month to 120 months (mean; 31±25.2 months). The factors that were analyzed for their effect on the patency of stents were age, the stent type and diameter, the lesion site, lesion shape, lesion length, the Society of Cardiovascular and Interventinal Radiology criteria, the total run off scores, the Fontaine stage and the cardiovascular risk factors (diabetes mellitus, hypertension and smoking). Follow-up included angiography and/or CT angiography, color Doppler sonography and clinical evaluation with the ankle-brachial index.ResultsTwo hundred and eighty-four stents were placed in 249 limbs of 203 patients. The technical success rate was 98% (203/206). The primary patency rates of the stents at 3, 5, 7 and 10 year were 87%, 83%, 61% and 49%, respectively. One hundred seventy-seven patients maintained the primary stent patency until the final follow up and 26 patients showed stenosis or obstruction during the follow up. Secondary intervention was performed in thirteen patients. Lesions in the external iliac artery (EIA) or lesions in both the common iliac artery (CIA) and EIA were a poor prognostic factor for stent patency. The run off score and stent diameter also showed statistically significant influence on stent patency. The overall complication rate was 6%.ConclusionIliac arterial stent placement is a safe treatment with favorable long term patency. Lesions in the EIA or lesions in both the EIA and CIA, poor run off vessels and a stent having the same or a larger diameter than 10 mm were the poor prognostic factors for long term stent patency.

“…Experimental data suggest that stents offer greater protection against thrombosis than angioplasty. [23][24][25] Stents have been quite useful in angioplasty procedures complicated by subintimal dissection or a residual stenosis, 11,12 and originally their use was advocated only in this setting. Early reports from a randomized trial suggested that iliac stent procedures had better patency than angioplasty alone, 13 but this has not been substantiated.…”

“…8,9 Stents were originally employed to treat complicated occlusive lesions, suboptimal balloon angioplasty results, and occluded iliac segments, 10 and following angioplasty-induced dissection. 11,12 Suggestions have appeared in the literature that the primary application of stents in all endovascular interventions may improve long-term patency, 13 but this has not been substantiated. Bolstered by these preliminary data and by the apparent angiographic and hemodynamic advantages of stent insertion, we and others 14 adopted a policy of routine stent insertion during iliac artery intervention in the early 1990s.…”
